Hi Elizabeth:

The big problem with cerberus is that there is already 1865 Cerberus, an
Apollo asteroid. IAU Nomenclatur Committee tries to avoid duplication like
that though there are several existing examples.

>>>>> Mountain View, Calif., who led this observing program with Hubble.

>>>>> Boulder, Colo. "Now that we know there's another moon in the Pluto

>>>>> The new moon is located between the orbits of Nix and Hydra, which

>>>>> Naval Observatory and first resolved using Hubble in 1990 as a
>>>>> separate body from Pluto.
>>>>>
>>>>> The dwarf planet's entire moon system is believed to have formed by a
>>>>> collision between Pluto and another planet-sized body early in the
>>>>> history of the solar system. The smashup flung material that
>>>>> coalesced into the family of satellites observed around Pluto.
>>>>>
>>>>> Lunar rocks returned to Earth from the Apollo missions led to the
>>>>> theory that our moon was the result of a similar collision between
>>>>> Earth and a Mars-sized body 4.4 billion years ago. Scientists believe
>>>>> material blasted off Pluto's moons by micrometeoroid impacts may form
>>>>> rings around the dwarf planet, but the Hubble photographs have not
>>>>> detected any so far.
>>>>>
>>>>> "This surprising observation is a powerful reminder of Hubble's
>>>>> ability as a general purpose astronomical observatory to make
>>>>> astounding, unintended discoveries," said Jon Morse, astrophysics
>>>>> division director at NASA Headquarters in Washington.
